My XH and I were married for 20 years. He had a 'mid life crisis'......had an affair with someone he worked with.Left me and our 2 children, as he wanted to be single and go out and do things......even though he did go out and do what he wanted whilst we were married. 5 years on, our 2 children are late teens, independent etc. Whilst XH has moved in with OW and her young daughter. OW's daughter is a similar age that our children were when he decided to be single and didn't want the responsibility of family and children. They are now, as a couple, doing all the things he would never do with me, weekends away, holidays without children etc. Why could he not do those things with me/us but can now do them with someone else and someone else's child? I have friends in a similar position and who say the same......it's like what we wanted to do was a complete no no but now all of a sudden they can do these things.....with OW other people's children.
